Sex Cord-Stromal Tumors – Sex cord-stromal tumors account for approximately 8% of all ovarian tumors.

Granulosa Cell Tumor Group – Granulosa cell tumors account for about 1.5% of all ovarian tumors and occur in a wide age range, from newborn to postmenopausal women
Thecoma-Fibroma Group – Thecoma occurs at any age but predominantly over the age of 40 years and rarely in children. Luteinized variants are more likely to occur in younger women

Sertoli-Stromal Cell Tumors – Sertoli cell tumors typically occur in young patients with a mean of 30 years; however, a wide age range exists. The tumors are more commonly estrogenic than androgenic

Sex Cord-Stromal Tumors of Mixed or Unclassified Cell Types – Sex cord tumor with annular tubules (SCTAT) is a tumor composed of sex cord (Sertoli) cells arranged in simple and complex annular tubules

Steroid Cell Tumors – Steroid cell tumors, not otherwise specified occur most often in women of reproductive age, particularly during the third and fourth decades, and rarely in postmenopausal women or children. They are clinically androgenic in 40% of cases and regularly secrete androstenedione, α-hydroxyprogesterone, and testosterone
